Radon Contractors in Richmond, Virginia
Radon testing and mitigation system installation..
Radon is a naturally occurring radioactive gas that seeps into homes through foundation cracks, gaps, and porous concrete. It's the second leading cause of lung cancer after smoking, and the EPA recommends mitigation for any home testing at or above 4 pCi/L. Radon mitigation typically involves installing an active soil depressurization (ASD) system — a vent pipe and fan that draws radon from beneath the foundation slab and exhausts it above the roofline. Professional radon mitigation systems reduce levels by 80–99% and cost a fraction of what most homeowners expect. Testing is inexpensive and should be done in the lowest livable level of the home.

General Radon FAQs
How much does radon mitigation cost?
A standard radon mitigation system (active soil depressurization) costs $800–$2,500 installed. Most homes can be mitigated with a single system: a 3–4 inch PVC pipe from beneath the foundation slab routed to above the roofline, with an inline fan creating negative pressure under the slab to draw radon out before it enters the home. The system runs continuously and uses about as much electricity as a 75-watt light bulb. Complex foundations (multiple slabs, crawl spaces, additions) may require additional suction points, increasing the cost. Post-mitigation testing should confirm levels are below 4 pCi/L.
How do I test my home for radon?
Short-term test kits ($15–$30 at hardware stores or free from many state health departments) provide results in 2–7 days. Place the test in the lowest livable level of the home with windows and doors closed for 12 hours before and during the test. Long-term test kits (90+ days) give a more accurate annual average. Professional radon testing ($100–$200) uses continuous monitors that provide hour-by-hour readings and is required for real estate transactions in many states. The EPA action level is 4 pCi/L — if your test result is at or above this level, mitigation is recommended.
